Upgrade for Windows 11 Support

Greetings! You can change out the motherboard, however, you'd have to find a used / refurbished one from a third party most likely that supports that CPU, as that series of CPUs / motherboards has been discontinued so unfortunately you wouldn't find a direct replacement at Micro Center. Anything currently sold by us wouldn't support a 5th gen Intel processor (oops, corrected by TSMichaelB), but that's what you'd be looking for.

The 6800K was Broadwell-E (5th gen), 6th generation would have been consumer Skylake on the 100 series chipset. Those were some confusing times back then.

@jrebele I would say @Yingdong is correct here, and that your cheapest route would be a TPM accessory (14-1 for that board in particular). The hard part is finding one, as they've gone up in price ever since Windows 11's TPM requirement announcement and can be quite scarce. You'll also likely need to ensure you are on the latest BIOS to avoid compatibility issues with the TPM accessory you buy.

If you are planning to upgrade the platform for Windows 11 compatibility, you'll unfortunately need a new motherboard and CPU. Your memory is DDR4 (they didn't make any DDR3 X99 motherboards, so we should be certain here, and I assume the 1223 is a typo of 2133). Anything 8th generation Intel or newer will work as well as AMD Zen+ or newer. For a full list of compatible processors, visit these pages:

Asus actually used to make a TPM module for that motherboard. You might shop around and see if you can find one.

But before you buy anything run the complete windows 11 upgrade system check and see if it also complains about the CPU or anything else. You don't want to buy a TPM module just to find that something else stops you.
